Blueberry pickers, ready your buckets because the bushes are bursting.Several U-pick blueberry farm owners across Snohomish County expect a boom crop this year.Eager blueberry pickers can get started on the bounty right away with a few U-pick farms that opened to the public this past weekend.But even if you don't get an early start, it sounds like there will be plenty of blueberries to go around.“We do have tons of blueberries starting to ripen now,” said Bob Fink.Fink and his wife, Patty Watson, run Penryn Farm U-Pick Blueberries in Lake Stevens, a small, honor-system farm on a private estate on Stitch Lake.The farm offers several varieties of blueberry bushes, some more than 40 years old.Penryn Farm will open to the public July 23. Fink said he anticipates having berries most likely through Sept. 10.“In fact, the berries on the bushes now are the biggest and most plentiful than we have ever seen,” Fink said.Fink said he generally gets a steady of stream of U-pick customers when the berries are on. He said people come for the low price – $2 a pound – and the varieties.“On the surface I'd say this is going to be a bumper crop this year, and we're now just hoping for some sunny warm weather,” Fink said.Keith Stocker of Mountainview Blueberry Farm in Snohomish called this year's blueberry crop “a heavy fruit load.”“Back in May when bushes were in bloom, we got a good pollination and we were getting the good weather we needed when the bees were working and that was key,” Stocker said.Keith and Janet Stocker, fourth generation farmers in the Snohomish River Valley, bought Mountainview in 2007. They run the farm along with their sons Ivan and Raleigh.Keith Stocker guessed he would open the U-pick operation July 21 and that the blueberry season would extend this year possibly through Sept. 20.“We will stay open as long as there is fruit to sell and customers to pick,” Stocker said. “We are a U-pick only farm and the only way the fruit leaves our field is by having customers pick it.”Some Snohomish County U-pick blueberry farms boast that their crops are 100 percent organic and some offer kid-friendly entertainment.One such farm, Donnelly's Riverbank Blueberries in Monroe, offers both.In addition to being 100 percent certified organic, Donnelly's has a pirate ship on their farm with pretend swords along with a “troll tree,” Pat Donnelly said.“We hand out bubble gum because if the kids are chewing bubble gum, they are not going to eat blueberries and that works,” Donnelly said.He said that some of his 750 blueberry bushes are so heavy with berries that the fruit is touching the ground.Donnelly's opened for U-pickers July 14.U-pick blueberriesHere's a list of several U-pick blueberry farms in the county.
